Description

Technical Field

[0001] The utility model belongs to the technical field of gears, and in particular relates to a one-way gear structure. Background Art

[0002] A one-way gear is a gear that transmits power in one direction and prevents reverse rotation. It is commonly used in the transmission systems of mechanical equipment such as fans, pumps, compressors, and bulldozers to prevent lateral movement of the equipment or avoid equipment stalling due to load changes.

[0003] Patent application number CN201110375278.3 provides a one-way gear comprising a first gear and a second gear concentrically mounted therewith. The second gear is mounted within the first gear. The first gear comprises an outer ring and a plurality of gear teeth disposed on the outer circumference of the outer ring. The inner circumference of the outer ring is provided with a plurality of first transmission teeth. The second gear comprises an inner ring and a second transmission tooth disposed on the outer circumference of the inner ring and capable of rotating toward a side of the first transmission tooth that matches the first transmission tooth. A support rod is provided on the side of the second transmission tooth that matches the first transmission tooth, with one end of the support rod connected to the second transmission tooth and the other end connected to the outer circumference of the inner ring of the gear. The support rod is provided with a spring, one end of the spring connected to the second transmission tooth and the other end connected to the outer circumference of the inner ring of the gear. This patent achieves one-way rotation of the gear, but the use of a spring requires a high elasticity of the transmission tooth material. The rebound of the second transmission tooth can easily cause vibration that affects the overall operation of the gear. Utility Model Content

[0004] The purpose of the utility model is to provide a one-way gear structure in order to solve the above problems existing in the prior art.

[0005] The objectives of the utility model can be achieved by the following technical solutions: a one-way gear structure, comprising an outer gear ring, an inner gear ring and a gear end cover; the outer gear ring comprises a structural spoke ring, the outer side wall of the structural spoke ring is uniformly formed with a plurality of continuous outer gear teeth in the circumferential direction, and the inner side wall thereof is uniformly formed with a plurality of raised discontinuous slide block blocks in the circumferential direction, one end of the slide block is transitionally connected to the inner side wall of the structural spoke ring, and the other end is formed with a blocking surface;

[0006] The inner gear ring includes a one-way spoke ring and an inner ring base integrally formed on the rear side thereof. The one-way spoke ring is evenly formed with concave and convex keyway rings on the inner side wall of the front end, and a plurality of groups of shaft fixing seats are evenly formed circumferentially on the outer side wall. The shaft fixing seats are a pair of coaxial ones in the front and rear directions. The shaft fixing seats in the same group are rotatably connected with a one-way slide through a rotating shaft. The one-way slide and the slide blocking block are slidably matched and one-way resisted against each other. The gear end cover is fixed between the front structural spoke ring and the one-way spoke ring by a threaded connection.

[0007] In the above-mentioned one-way gear structure, inner ring internal threads are provided on the inner side walls of the one-way spoke ring and the inner ring base at the rear side of the keyway ring.

[0008] In the above-mentioned one-way gear structure, an inner ring external thread is provided on the outer side wall of the one-way spoke ring in front of the shaft fixing seat, and an end cover internal thread is provided on the inner side wall of the gear end cover. The end cover internal thread and the inner ring external thread cooperate with each other to fix the gear end cover between the outer gear ring and the inner gear ring.

[0009] In the above-mentioned one-way gear structure, the top of the shaft fixing seat is in the shape of an arc, and the two ends of the one-way sliding plate in contact with the shaft fixing seat are in the shape of an inwardly concave arc.

[0010] In the above-mentioned one-way gear structure, a pair of mounting holes are symmetrically provided on the gear end cover.

[0011] Compared with the existing technology, the one-way gear structure provided by the utility model realizes the one-way rotation of the gear through the mutual sliding cooperation and one-way offset between the one-way slider and the slider blocking block, and is not prone to generating unnecessary vibration during one-way rotation, which can effectively ensure the stable operation of the one-way gear.

DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figures 1 to 3As shown, this one-way gear structure comprises an outer gear ring 100, an inner gear ring 200, and a gear end cover 300. The outer gear ring 100 is coaxially sleeved on the outer side of the inner gear ring 200. A removable gear end cover 300 is fixedly connected between the outer gear ring 100 and the inner gear ring 200 at the front side via a threaded connection. A pair of mounting holes 320 are symmetrically opened on the gear end cover 300 to facilitate maintenance of the internal one-way structure.

[0018] like Figures 2 to 3 As shown, the outer gear ring 100 includes a structural spoke ring 110, and a plurality of continuous outer gear teeth 120 are uniformly formed on the outer side wall of the structural spoke ring 110 in the circumferential direction, and a plurality of protruding discontinuous slide block blocks 111 are uniformly formed on the inner side wall thereof in the circumferential direction. One end of the slide block 111 is transitionally connected to the inner side wall of the structural spoke ring 110, and a blocking surface 112 is formed on the other end.

[0019] The internal gear ring 200 comprises a one-way spoke 210 and an inner ring base 220 integrally formed at its rear side. The one-way spoke 210 has a concave and convex keyway ring 211 formed uniformly on its front inner sidewall. The keyway ring 211 is used to key the one-way gear onto the working shaft. Several sets of shaft fixing seats 213 are uniformly formed circumferentially on the outer sidewall of the one-way spoke 210. Each set of shaft fixing seats 213 consists of a pair of coaxial front and rear shafts. One-way slides 230 are rotatably connected to each other within a set of shaft fixing seats 213 via a rotating shaft 231. The tops of the shaft fixing seats 213 are arc-shaped, and the ends of the one-way slides 230 that contact the shaft fixing seats 213 are concave arc-shaped. The one-way slide plate 230 is slidably engaged with the slide plate blocking block 111 and is unidirectionally opposed to each other. During the one-way sliding process, it is squeezed by the inner side of the slide plate blocking block 111, causing it to rotate and adjust around the rotating shaft 231 until it slides to engage with the blocking surface 112.

[0020] To further illustrate, the inner sidewalls of the one-way spoke ring 210 and the inner ring base 220 are provided with inner ring internal threads 221 behind the keyway ring 211. The outer sidewall of the one-way spoke ring 210 is provided with inner ring external threads 212 in front of the shaft fixing seat 213. The inner sidewall of the gear end cover 300 is provided with end cover internal threads 310. The end cover internal threads 310 and the inner ring external threads 212 cooperate to securely connect the gear end cover 300 between the outer gear ring 100 and the inner gear ring 200.

[0021] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0022] Although various terms are used in this document, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
